    Default Getting wifi to work from the CLI

    Hi Everybody,
    I am on OpenSuse11. My wifi works fine when
    I use knetworkmanager. But now I have installed
    xmonad and don't want to use a GUI to get my
    wifi working. But without knetworkmanager, I
    can't seem to get my wifi working. When I use
    iwconfig, I get:
    linux-w402:/home/santanu # iwconfig
    lo no wireless extensions.

    eth0 no wireless extensions.

    using iwconfig I can set the essid value,
    but whatever I do, I can't get the wifi to
    get associated with the access point. Well,
    "/etc/init.d/network restart" does it, but
    then as soon as I use dhclient on the eth1
    interface, it again becomes unassociated.
    I am quite new to this wifi thing and I
    must be missing something here (no
    authentication is being used).

    Could you please point me to some documentation
    that explains in details how to get wifi
    associated with an access point from the

    Perhaps network manager is still interfering in the background?

    You can tell SuSE not to use network manager at all under the "Global Options" tab in the "Network Settings" dialog in YaST.

    Set it to the "traditional ifup" way of configuring the network, and maybe network manager will stop interfering then.

    ifup / ifdown is the way SuSE used to configure the network in the old days, and is well documented on the googleinterwebnet.

    Thanks. I think you are right. I found that the following
    two commands bring my wifi connection running:
    # service network stop
    # ## At this point iwconfig shoes 'Associated' !
    # dhclient eth1
    # ## At this point, my wifi is up with an ip address
    # ## acquired from the wifi router
